REPEATING-COUNTER- To. all 'whom 'it may concern Be it .known that I,VViLLIAM GRUNOW,

I Jr., a citizen of the United States, residing at Waterbury, in thecounty of New Haven and State of Connecticut, have invented a new anduseful Improvement in Repeating- Counters; and I do hereby declare thefollowing, when taken in connection with the accompanying drawings andthe .characters of reference marked thereon, to be a full,

. clear, and exact description of the same, and

' my invention.

which said drawings constitute part of this application, `andlrepresent, in-

Figure 1 a top or plan view of a repeating counter constructed inaccordance with Fig. 2 aside view of the same,` showing the mechanismadapted to movefin one direction. Fig. 3 a similar view showing themechanism adapted to move in the opposite direction. Fig. 4 a side viewthe reverse of Figa- 2 and 3. v Fig. 5 a broken sectional view showingmeans for fixing the c position of the index.

This invention relates to an improvement in repeating counters, theobject being to provide a counter which will operate a predeterminednumber of times' in one direction, then reverse and operate an equalnumber of times; for instance, where three op erations are performed theIdevice will opcrate in one direction three t-im'es, then reverseandoperate three timer, and repeat this counting by .three as lo gasrequired, and at thesame time register the number of serieso'f three orany other predetermined- As another instancev of 'use 1n number.measuring thread, the. device can be adjusted to operateat the end'ofeach hundred yards and register the number of hundred yards passing; andthe invention 'con.

of the screw shaftv with respect to its threads,

a pin 9 may be passed through the end of thepost 8 and into the threadedshaft 7. On thisscrew sh'aft'are mounted a stopwheel10 and anindex-wheel 11 provided respectively with threaded hubs 13 and 12 whichfree'lyJit they screw shaft 7 to permit of being rotated about thesame.The stopwheel 10 is toothed'and meshes with the. A

`pinion 3 by which it is driven andcaused to rotate about the screwshaft 7,' and to travel lengthwise with its axis, whereby the wheel 10is caused to travel spirallyx Theindexwheel 11 preferably has itsrimgraduated into divisions corresponding with the number of teeth in thestop-wheel V10. Around` the hub 12 is a split collar 52 the ends ofwhich are.. connected by a screw 14 by which theihub may befconnectedwith the screw shaft 7. The collar 52 is also provided with an outwardlyprojecting index-arm 15 which is perforated at its outer end for thepassage through `it of a graduated rod 16 'hereinafter referred to.IPassing.through `the screw shaft'7 is a freely fitting shaft 17 whichis firmly secured at one end`to an `arm 187Which supports one end of thegraduated rod `16, the divisions of which correspond with the pitchofthe screw shaft 7. The other end of the graduated rod is mounted in anarm 19 fixed to the' shaft 17. A double pawl 20 is mqunted on a stud 21mounted in the outer end of a crank arm of alever. 23 which is pivotallymounted on the base which base is providedwith stop-lugs`24'and 25 tolimit the movement of the lever. The double paWl 20 comprises an upperpawl' 26 and a lower 'pawl 27 adapted to engage with the teethof nthesprocket wheel v2, one pawl causing the sprocket to' turn in onedirection and the other in the opposite direction, the lengt-h of thestroke bein fixed by the said stop-lugs 24l and 25. To t(Iiold thesprocket wheel during the return stroke of either of the pawls, i Iemploy a detent 28, and to causel the return movement of the pawlsIemploy a spiral spring 29. slde of the double pawl 20 are two plus 30,3l, between which al flexible strip 32 extends, thisstrip being fixed tothe arm 18, and at theother end extending over the stud 21 von which thedouble pawl is mounted, the outer end of this stud being flattened, andso that the strip 32 may have a bearing upon 'IUv Projecting outwardfrom one continued operation of the lever 23 then re-` either the upperor lower side of the fiattened portion. To provide a lock for the armslSvand 19 in the two positions, I mount` a locking-lever in a bracket 34secured to the base 6, and form this locking-lever with two notches 35,36, either of which may be engaged by the graduated rod 16, thelcverbeing forced against the rod by a spring 3T.' The lever is also providedat its upper end with a hammer-arm v38 which will engage with a bell 39when the graduated rod is shifted. The stop-wheel 10 is provided with anactuating pin 40 projecting from opposite sides, and the index-wheel 11is provided with a count pin 41 adapted`- to be engaged by one end ofthe actuating pin 40, the other end of which pin 40 is adapted to engagewith the arm 18. The indexwheel 11 being set at the desired point andthe lever 23 operated, will cause one or the other' of the pawls 26 or27 to engage with the sprocket 2.

As shown in Fig. 2 of the drawings, the pawl 26 will/engage with t-hesprocket wheel 2 and each downward movement of the lover 23 will turnthe sprocket one tooth and move the wheel 10 a corresponding degree. Atthis time the strip 32 bears against the lowerpin 31 carried by thedouble pawl, and the graduated rod 16 is held by the upper notch 36 inthe lever 33. A continued operation of the vlever 23 will move thestopwheel 10 a predetermined number of times and until theactuating-pin40 carried .by the wheel 10 engages with the count-pin 41carried by the index wheel 11, and these pins are so arranged that thestop-pin 40 will en'- gage with the top of the count-pin 41 so as todepress the graduated rod 16, and hence depress the arms'18 and 19, andthis depression of the arm 18 shifts the double pawl 20 so that thelower pawl 27 is in position" to engage the teeth of the sprocket 2.'The verses the movement of the pinion 3 and hence reverses the movementof lthe stopwheel 10 which will turn upon the screw shaft 7 until theopposite end of the stoppin 40 engages with the underside of the arm 18.The number of movements necessary to cause this engagement, being thesame as was required in the opposite irection, so that b adjusting'theindex-wheel 11 on the screw s yaft 7, the sprocket wheel may be movedone tooth in one direction, then reverse and move one tooth in theopposite direct-ion, or it may be adjusted so that one thousandor moremovements in one direction are necessary to bring the stop-pin intoengagement with the index-wheel, and the vsame number of operationsy inthe return direction; and at each shift .the bell will be sounded. Fixedto the end \of the shaft 17 is a lever' 42 which operates a'series ofconntilngwheelsl43, 44 Vvand 45 usual ccnstruction by which each shiftof the graduated rod is registered, thus indicating at once the numberof series of any predev termined number.

Instead of operating the pawls b the lever 23, the pawls may be operatedy an eccentric 46 mounted on a shaft 47 andadapted to engage with thestud 21on which the double pawll is mounted. This shaft may be turned bymounting a worm wheel 48 upon it and providing a worm 49 on a shaft 50operated by a grooved o'r other wheel 51 by which the worm maybe turned.This wheel would be of such size that a predetermined number ofrevolutions would operate the cam at the desired time to move the pawls;for instance, in measuring thread, the wheel could be of suchl size thateach one, or two, or three, or any other number of hundred yards ifpassed over it would shift the pawls.

I claim:
